Expert Answer:

I t - 2 I this means velocity is -(t-2) for t less than 2 seconds and (t-2) for t greater than 2 seconds.

Also the velocity is zero for t = 2s.

v(t) = -(t-2) for t<2

      = 0  t=0

      = (t-2) for t>2

Distance is total area under velocity vs time graph,

= Area of the two triangles on the graph (shaded are)

= 4 m
